Build a Twitter Like Search Feed with React.js and appbase.io. This is Part — II of a series on building Twitter like live search feeds with different Javascript frameworks.

You can check out the Part-I published on scotch.io where we used jQuery. Ever tried Twitter Live Search and wondered how it works?

# Enter meetupblast! ( Key Ingredients # Deep Dive. Making your JavaScript Pure. Once your website or application goes past a small number of lines, it will inevitably contain bugs of some sort.

This isn’t specific to JavaScript but is shared by nearly all languages—it’s very tricky, if not impossible, to thoroughly rule out the chance of any bugs in your application. However, that doesn’t mean we can’t take precautions by coding in a way that lessens our vulnerability to bugs. Pure and impure functions#section1 Article Continues Below A pure function is defined as one that doesn’t depend on or modify variables outside of its scope.

Take this function that calculates whether a user’s mouse is on the left-hand side of a page, and logs if it is and otherwise.
